When I saw it I was hoping it would be what it's title promised. A place to find explanations of words used Aikikai, Yoshinkan, Shodokan, Ki Society lineages at least. But it really should be called "Aikikai Terminology" and from what Jun says it sounds like not even all of that.

Would have been a more interesting project if he had done some more research.
still the sample was interesting to peruse.
